They told me that they estimated my speed would be ~13-14Mbps down and 1.2Mbps up on ADSL2 and ~17-18Mbps down and 7Mbps up with a 8db attenuation.
I have a feeling I may stick with ADSL until fibre is available as there’s not a lot more speed for $30/month
That *may* be a fairly conservative estimate. The online VDSL speed estimate they used to have gave me an estimate of 18-19 Mbps for my address (Not sure if snap still have that on their website) At the time another ISP did a pre-qual and came back with an estimate of ~25Mbps I believe.
Both were conservative (the snap one very conservative) as I'm now on VDSL and syncing at 36/10 and get actual throughput of 33\9.5+ YMMV of course but that was how mine ended up :)
